ATILA Modal Analysis
This solver includes the modal analysis of elastic, piezoelectric, magnetostrictive structures, closed fluid domains, and closed hydroelastic systems. A unique variant of this modal analysis is also included and efficiently performs the computation of the resonance and antiresonance modes of piezoelectric and magnetostrictive structures, as well as the effective coupling coefficient. Results include normal frequencies and normal modes, and effective coupling coefficient.
Below is the modal analysis case for Amplified Piezoelectric Actuator. The basic structure is a piezoelectric element inside a metal shell for displacement amplification.
ATILA provides resonance and anti-resonance frequencies along with coupling factors. It helps identification of main resonance mode and detecting undesired spurious modes.
